      Without the interrupt you'll get problems if you enable
CONFIG_RTC_DRV_MAX77686.  Setup the interrupt properly in the device
tree.

      ARM: vexpress/TC2: Implement MCPM power_down_finish() · 33cb667a
      Dave Martin authored 
      This patch implements the power_down_finish() method for TC2, to
enable the kernel to confirm when CPUs are safely powered down.

The information required for determining when a CPU is parked
cannot be obtained from any single place, so a few sources of
information must be combined:

  * mcpm_cpu_power_down() must be pending for the CPU, so that we
    don't get confused by false STANDBYWFI positives arising from
    CPUidle.  This is detected by waiting for the tc2_pm use count
    for the target CPU to reach 0.

  * Either the SPC must report that the CPU has asserted
    STANDBYWFI, or the TC2 tile's reset control logic must be
    holding the CPU in reset.

    Just checking for STANDBYWFI is not sufficient, because this
    signal is not latched when the the cluster is clamped off and
    powered down: the relevant status bits just drop to zero.  This
    means that STANDBYWFI status cannot be used for reliable
    detection of the last CPU in a cluster reaching WFI.

This patch is required in order for kexec to work with MCPM on TC2.

MCPM code was changed in commit 0de0d646 ('ARM: 7848/1: mcpm:
Implement cpu_kill() to synchronise on powerdown'), and since then it
will hit a WARN_ON_ONCE() due to power_down_finish not being implemented
on the TC2 platform.

      ARM: tegra: Provide dummy powergate implementation · 9886e1fd
      Thierry Reding authored 
      In order to support increased build test coverage for drivers, implement
dummies for the powergate implementation. This will allow the drivers to
be built without requiring support for Tegra to be selected.

This patch solves the following build errors, which can be triggered in
v3.13-rc1 by selecting DRM_TEGRA without ARCH_TEGRA:

drivers/built-in.o: In function `gr3d_remove':
drivers/gpu/drm/tegra/gr3d.c:321: undefined reference to `tegra_powergate_power_off'

From Tony Lindgren:

Also few randconfig build fixes and removal of some dead code for omap4
as it no longer has legacy platform data based booting support.

      ARM: omap: fix warning with LPAE build · 6dd1e357
      Olof Johansson authored 
      Some omap3 code is throwing a warning:
arch/arm/mach-omap2/pm34xx.c: In function 'omap3_save_secure_ram_context':
arch/arm/mach-omap2/pm34xx.c:123:32: warning: cast to pointer from
  integer of different size [-Wint-to-pointer-cast]

In reality this code will never actually execute with LPAE=y, since
Cortex-A8 doesn't support it. So downcasting the __pa() is safe in
this case.
